High-profile celebrity magazine editor Bonnie Fuller is resigning as executive vice president and chief editorial director of American Media Inc, the publisher of the National Enquirer and Star magazines.

The company said on Tuesday that Fuller will become editor-at-large at Star and serve as a consultant to Chairman and Chief Executive David Pecker.

It’s unclear why Fuller is leaving the job.

“I am proud of the significant achievements of American Media’s celebrity and fitness brands over the past five years, and I am now ready for a new adventure,” Fuller said.
